Popis:	A simple algorithm for calculating three-mirror telescopes with all conic surfaces free of spherical aberration, coma, astigmatism, and field curvature is proposed. The algorithm is based on the theory of aberrations of the third order. The initial parameters are the effective focal length, mirror diameters, and system length. The result is a design with a flat field of view with a diameter of more than 1° at sub-arcsecond image quality, which is close to the theoretically best. If necessary, the latter is achieved through slight optimization.
